Red Mansion: Did I Get the Wrong Time-Travel Script?

I am a criminal policeman who traveled through the Red Mansion and became a third-generation slave named Jiao Da. By rescuing Qin Keqing, she obtained the Beauty Change Luck System. And through his own understanding of the characters in Red Mansions and his disagreements with book fans, he changed the fate of half of the Twelve Hairpins of Jinling. The remaining half may really hate this character. Of course, by accumulating points by changing the fate of others, he also changes Jiao Da's own fate, fate, and achievements. Finally, the Ming Dynasty waved its flag and went north to annihilate the Jurchens and preserve Chinese orthodoxy.
